Under The Landlord and Tenant Act, R.S.M. 1987, c. L70, unlike residential tenancy — where Manitoba law mandates landlords provide standard forms and proactive disclosures — commercial leasing operates primarily under the principle of caveat emptor (let the buyer/renter beware). The burden of discovery falls on the tenant, and there is no general statutory duty to disclose all "material facts." However, landlords face liability for failing to disclose specific dangerous defects or environmental conditions.

The Limited Statutory Disclosure Requirement

There are very few specific statutory disclosures required under The Landlord and Tenant Act for commercial properties. There is no mandated "Standard Commercial Lease" and no prescribed disclosure checklist.

Instead, the commercial landlord's disclosure obligations arise primarily from:

  1. Duty to disclose latent defects — Known hidden defects that make the property dangerous or unfit for the purpose for which they are leased (4781101 Manitoba Ltd. v. J.S.L. Holdings Ltd.).
  2. Statutory environmental obligations — Under The Contaminated Sites Remediation Act, C.C.S.M. c. C205, s. 17(1), landlords must provide a written statement if they know or should reasonably know a site is contaminated.
  3. Asbestos Inventory — Under the Workplace Safety and Health Regulation, M.R. 217/2006, s. 37.2, owners must maintain and provide an asbestos inventory to occupants.
  4. Common law duty not to misrepresent — Active misrepresentation or fraudulent concealment of material facts is actionable.

Areas Where Disclosures Are Expected

Despite the lack of explicit statutory forms, common law and specific regulations require a commercial landlord to disclose several categories of information:

1. Environmental Hazards and Contamination

Environmental disclosure is a strictly regulated area of commercial landlord liability in Manitoba:

HazardDisclosure StatusLegal Basis
Known Contaminated SitesMandatory written statementThe Contaminated Sites Remediation Act, s. 17(1)
Asbestos-containing materialsMandatory inventory/management planWorkplace Safety and Health Regulation, s. 37.2
Soil/Groundwater contaminationMust disclose if knownThe Contaminated Sites Remediation Act
Underground storage tanksMust disclose if knownEnvironmental cleanup liability
MouldShould disclose if significantHealth claims, remediation costs
Lead paintShould disclose in older buildingsHealth liability
PCBsMust disclose if knownRegulatory penalties

Environmental Site Assessments (ESA):

  • Phase I ESA — A desktop review and site inspection identifying potential contamination.
  • Phase II ESA — Soil and groundwater sampling to confirm or rule out contamination.
  • Landlords often provide Phase I ESA reports to prospective tenants to document the baseline environmental condition and properly apportion future cleanup liabilities.

2. Zoning and Permitted Use Restrictions

While a tenant must ultimately verify that municipal zoning permits their specific business, the landlord must disclose:

  • Any known restrictive covenants on the property title.
  • Exclusivity clauses already granted to other tenants in the same complex.
  • Any pending zoning changes or development applications the landlord is aware of.
  • Heritage designations that may restrict alterations to the building.
  • Access restrictions that may affect the tenant's operations (e.g., restricted loading dock hours).

Exclusivity Clause Disclosure

In multi-tenant complexes, exclusivity clauses are particularly important:

ExampleDisclosure Obligation

| Promising a pizza restaurant they will be the only pizza vendor | Must disclose to all prospective food tenants | | Granting a pharmacy exclusive rights to sell health products | Must disclose to all prospective health/wellness tenants | | Restricting a tenant from selling coffee in a complex with a café | Must disclose the restriction to the incoming tenant |

3. Structural and Latent Defects

A landlord who is aware of a significant, hidden structural defect (a "latent defect") that renders the property dangerous or unfit for the tenant's known intended use must disclose it:

  • Patent defects (visible upon reasonable inspection) — No duty to disclose; tenant should have discovered them.
  • Latent defects (hidden, not discoverable through reasonable inspection) — Must be disclosed if they make the premises dangerous or unfit and are known to the landlord.
  • Fraudulent concealment — Actively hiding or masking a known defect (e.g., painting over water damage, covering cracks) may constitute fraud.

4. Operating Costs (TMI/CAM)

There is no statutory requirement under Manitoba law for a landlord to provide historical operating cost statements (TMI/CAM). These disclosures are strictly governed by the terms of the lease agreement or the offer to lease.

Disclosure (Contractual)Purpose
Historical operating cost statementsAllows tenant to verify cost trends (if required by lease)
Current year budget estimateBasis for monthly additional rent prepayments
Property tax assessment noticesVerifies tax component of additional rent
Insurance premium summariesDocuments insurance cost trends
Capital expenditure historyIdentifies major upcoming expenses
Management fee structureClarifies the property management cost allocation

5. Building Code Compliance

Landlords should disclose:

  • Any outstanding building code violations or work orders.
  • Recent fire inspection results and any required remediation.
  • Elevator inspection certificates and compliance status.
  • Any accessibility compliance issues under The Accessibility for Manitobans Act.

6. Tenant Default History

While not legally required, sophisticated tenants may request:

  • The occupancy rate and tenant turnover history.
  • Any pending or recent litigation involving the property.
  • The financial health of the property (particularly for CAM-heavy multi-tenant buildings).

Risks of Non-Disclosure

If a landlord fails to disclose required information, the consequences can be severe:

RiskPotential Outcome
Misrepresentation claimTenant may rescind the lease and claim damages
Fraudulent concealmentPunitive damages, potential criminal liability
Environmental liabilityLandlord may be liable for cleanup costs under The Contaminated Sites Remediation Act
Negligence claimIf non-disclosure of a dangerous latent defect causes injury
Lease rescissionCourt may void the lease entirely

The Tenant's Due Diligence Obligation

While landlords have specific disclosure duties, the commercial tenant also bears responsibility:

  1. Inspect the premises — Conduct thorough physical inspection before signing.
  2. Commission an ESA — Obtain environmental assessments for industrial or historically contaminated sites.
  3. Verify zoning — Confirm municipal zoning permits the intended use.
  4. Review building systems — Inspect HVAC, electrical, plumbing, and fire suppression.
  5. Check title — Review the property title for encumbrances, easements, and restrictive covenants.
  6. Review CAM records — Audit historical operating cost statements if permitted by the lease.

Best Practices for Landlords

  1. Disclose Latent Defects — Ensure any known defects that impact safety or fitness for use are disclosed in writing.
  2. Provide Contamination Statements — Comply with The Contaminated Sites Remediation Act by providing written notice of known contamination before lease execution.
  3. Maintain Asbestos Records — Keep a current asbestos inventory as required by workplace safety regulations.
  4. Document all disclosures — Provide disclosure information in writing and retain copies.
  5. Include representations and warranties — Address property condition, environmental status, and zoning in the lease.
  6. Update exclusivity schedules — Maintain a current list of all exclusivity clauses for reference during leasing.
  7. Consult legal and environmental professionals — Engage lawyers and environmental consultants for properties with complex disclosure requirements.
